Re: [Boost-users] Fastest way of serializing a huge vector of ints into a human readable string

Ovanes, ok, got it! Thanks for the nice examples and your patience. I learned a lot today :-) In the meantime I created my own FormattedBackInserter (see attached code, just a very crude prototype as of now), which allows me to do the job even faster via std::copy.

Ovanes,

I wonder, though, is there a standard way to write integers to a stream_buf? As far as I can see, the ostreambuf_iterator takes character classes as template arguments, only.

Roland,

please take a look at this code: http://codepad.org/UGubU7cw

It it always customized numeric converter is almost always faster as writing integers to stringstream with operator<<. Anyway these two tests perform most equally on linux/g++ (but tested very roughly). For Example on MSVC-compiler std::copy was faster as the for-loop. I assume compiler can better optimze in this case.

Good Luck, Ovanes
